CNC Lathe Chucks

CNC lathe clamping device, chuck is *, although now there is a pneumatic chuck, but the pneumatic chuck is limited to small pieces of rapid processing, chuck naturally become irreplaceable products.

Machine tool chuck type and selection

Selection of self-centering chucks

This product is suitable for K11 series short cylindrical, K11 short conical, K11 (QT) ductile iron K11 (G) steel three-jaw self-centering chucks, all the contents in the product are only for the user's reference when using and maintaining. For further information, users are welcome to consult with our customer service department and give valuable comments on the product in the course of use.

● a. Although the cnc lathe chucks meets the requirements of the standards, hazards may be produced by the characteristics of the work and machine. To eliminate hazards, the user should consider the characteristics of the workpiece (e.g., size, mass, and shape) and the characteristics of the machine (e.g., speed, feed, and depth).

● b. The user should determine the maximum permissible speed of the machine based on the required clamping force, which must not exceed the maximum rotational speed of the chuck.

● c. For special top jaws, the user should use static clamping force measuring equipment to check the maintenance condition according to the maintenance instructions.

● d. Residual hazards may occur if satisfactory rotational balancing qualities are not achieved.

● e. To avoid overloading a particular chuck, the effective force from the machine should be reduced.

K11 series three-jaw self-centering chuck adopts plane thread structure, through the gear, disc wire, make the jaws move at the same time, to realize automatic centering of the workpiece. The short taper chuck can be directly mounted on the spindle of the machine tool, and has the characteristics of short overhang, strong rigidity, high centering accuracy, easy installation, etc. Ductile iron chucks, made of fine machining, have higher speed, higher clamping force, etc. Steel chucks have the advantages of high rotational speed, high clamping force, and long service life.

Users should be based on the dimensional requirements of machined parts, according to the permissible clamping range of the chuck, the selection of the appropriate chuck, and the chuck's opening of the new situation holding range.

First use of the card should also consider the main parameters of the machine tool used, such as limiting speed, through-hole and other aspects.

● a. The size of the workpiece blank should be within the clamping range, must not exceed, or cause danger.

● b. Use the appropriate through-hole size according to the workpiece options.

● c. Clamping force should meet the cutting requirements.

● d. The required speed should be within the limit speed this.
